knock-up

A short practice session before a tennis match.

In the way of friendly knockups I played at times with both the Renshaws and Lawford, but at that time there is no doubt that they were better than I was.

Something constructed shoddily or hastily.

One of those unadorned late-fifties hillside knockups posing as intentionally contemporary but really the product of a tight construction budget.

A pregnancy.

When will we wake up? I see young girls pregnant and young boys adding up their “knock-ups” like a scorecard at a mob gambling venue.
